WHAT  RAILWAY   BALLAST   MAKERP   SAY   OF   THE  GATES   BREAKER. 


„     ,  Choate,  Del.,  Feb.  14, 1888. 

Gentlemen:— \oms  of  the  gth  inst.  received.  We  t.ike  pleasure  in 
giving  our  testimony  as  to  the  superiority  ol  your  Breaker  over  all 
others.  We  have  used  no  otiier,  but  have  seen  them  and  know  their 
capacities  and  weak  points,  and  have  had  positive  proof  of  their 
inferiority  to  Gates'  machir..  We  know  that  our  stone  could  not  be 
broken  into  ballast  by  any  other  machine;  that  is,  continuously,  ow- 
ing to  its  great  hardness. 

We  consider  your  claims  for  it  entirely  reasonable,  as  we  have 
found  the  machine  able  to  do  more  work,  break  more  stone  than 
we  were  able  to  deliver  to  it  in  any  one  whole  day. 

The  repairs  have  been  very  reasonable,  considering  the  amount 
and  character  of  work  done,  and  much  less  than  other  machines, 
which  we  learn  from  others  using  them.  We  positively  think  it  the 
greatest  machine  on  earth  for  the  puriwse,  and  have  a  very  enthusi- 
astic  opinion  of  it.  Youts  truly, 

J.  15.  IIIZAR  &  SON.

Dear  Sti-s:~\n  reply  to  yours  of  the  25th  inst.,  would  say  fhat  the 
Gates  Breaker  gives  us  satisfaction.  We  have  three  Breakers,  one 
Size  3  and  two  Size  7.  With  our  plant  we  can  break  90  cars  in 
lo  hours.  I  cannot  say  how  long  the  concaves  will  last.  Our 
Breaker  we  have  run  for  hoo  years,  and  have  not  spent  a  cent  for 
repairs,  and  I  think  the  concaves  are  good  for  hit  years  more.  Our 
stone  is  very  hard  limestone.  I  expect  to  break  7,(xx)  cars  of  bal- 
last this  summer,  and  I  would  not  give  a  man  one  dollar  to  guarantee 
the  expense  of  the  Breakers,  outside  of  oil.  I  took  a  gentleman  to 
see  one  of  ours  last  week;  the  weather  was  cold;  he  timed  4  cars  in 
42  minutes;  they  weighed  I56,oo(i  pounds. 

Very  truly,  E.  L.   REED, 

President.

Gentlemen :—\xi  reply  to  your  favor  I  wish  to  say  that  our  Breaker 
Size  6,  .at   Pearl,   is  working  tine,  and  is  giving  entire  satisfaction, 
breaking  on  an  average  230  cubic  yards  per  day  of  ten  hours.

Port  Chester,  N.  Y.,  Feb.  20,  1888. 
Dear  Sirs:—'^t  have  been  working  from  six  to  ten  Rock  Breakers 
for  the  last  fifteen  yet  s.  Among  those  used  were  three  from  the 
Gates  Iron  Works  of  Chicago  (one  Size  3,  one  Size  4,  and  one  Size 
6).  We  have  no  hesitan;y  in  saying  the  "Gate;,  Rock  Breaker"  is 
far  superior  to  all  others.  It  hasevery  advanti.ge.  ist.  In  quantity 
of  stone  broken,  about  three  times  as  much  as  in  a  flat  jaw  breaker. 
2d.  In  uniformity  of  size  of  stone  broken,  no  spalls  or  flat  pieces. 
3d.  A  saving  of  from  30  to  40  per  cent,  of  power  by  actual  tests. 
4th.  A  saving  of  from  25  to  50  per  cent,  to  keep  in  repair.  5th.  The 
continuous  discharge  prevents  packing  or  pulverizing.  We  could 
enumerate  many  more  advantages  your  Breaker  possesses,  and  to 
sum  it  up  will  say,  your  machine  is  entitled  to  all  you  claim  for  it. 
Very  respectfully, 

CARPENTER  BROS. 


Alton,  III.,  Feb.  11,  1888. 
Deat   Sirs: — You  ask  me  what  I  think  of  your  Breaker.     I  have 
used  one  of  your  Size  6  Breakers  since  1881,  and  consider  it,  as  you 
claim  for  it,  "The  Best  on  Earth."     In  fact,  would  not  use  any  other. 
I  am  breaking  25  carloads  of  stone  ballast  daily,  the  cars  averaging 
30,000  lbs.  to  the  car.     Our  stone  is  a  hard  limestone.     The  repairs 
have  been  very  li;^ht  during  the  seven  yews  it  has  been  running.     So 
can  cheerfully  recommend  your  Breaker  as  being  the  best  made. 
Vours  respectfully,

Gents:— y^c  used  the  first  Breakers  made  by  you  of  each  of  three 
different  sized  patterns.  After  several  years'  service  breaking  100  to 
1 50  tOiis  of  stone  per  day  with  the  large  machine,  and  less  than  five 
dollars  per  year  for  repairs,  the  Jiieakcr  is  as  good  to-day  as  wlien  it 
came  from  the  shop.  I  think  it  is  the  best  Breaker  that  I  have  ever 
seen,  and  think  there  can  be  nothing  better.  We  are  all  well  satis- 
fied with  it.  Most  respectfully  yours,

you  the  opinion  of  those  who  l)ought  from  us,  and  that  is  wonder- 
fully in   favor  of  the  dates   P.reaker.     The  eight  or  ten  breakers  we 
have  sold  have,  without  exception,  given  satisfaction,  and  as  to  re- 
pairs, we  have  not  ordered  two  hundred  dollars  worth  of  repairs  in 
five  years.     One  of  our  largest  customers  says,  if  any  one  wants  a 
breaker  and  does  not  buy  a  dates,  he  simply  docs  not  know  his  busi- 
ness.    We  have  two  customers  foi'  large  breakers  this  spring.

Gentlemen :—^\\e  bought  of  your  house  a  Size  3  ISreaker,  and  sub- 
sequently bought  a  Size  6,  which  we  have  now  been  running  almost 
constantly  for  four  years,  breaking  limestone  for  Macadam,    It  gives 


us  pleasure  to  indorse  your  Breaker  as  all  and  more  than  you  claim 
for  it.  We  have  practically  h.id  nf)  repairs  in  the  entire  time  the 
Breaker  has  been  running.  We  can  break  a  ton  of  Macadam  or  or- 
dinary road  metal  a  minute  in  it,  when  able  to  get  the  stone  to  it  It 
will  take  in  stone  11  by  24  in  each  of  three  f)pcnings. 

In  short,  it  breaks  more  stone,  takes  less  power  and  less  repairs 
than  you  allow  for  it  in  your  cat.-.logue.  'I'lie  result  of  ycarsof  expe- 
rience has  convinced  us  that  your  Kock  Bre.iker  has  no  e(iual.  The 
latest  patterns  of  Jaw  Breakers  cannot  compete  with  your  ISreaker, 
each  receiving  and  discharging  the  same  sized  stone.  The  secret  of 
your  advantage  lies  in  !he  mechanical  f.ict  that  there  is  no  lost  time 
with  your  Breaker,  /t  is  constantly  fireai-ini;.  Vour  devices  for  oil- 
ing, the  perfection  of  your  journals,  the  simplicity  of  design  and  lack 
of  parts,  are  all  mechanical  points  of  the  highest  excellence.  Your 
Breaker  does  not  require  experienced  machinists  for  running  it.  The 
shape  of  the  breaking  surfaces  produces  the  most  perfect  cubes  for 
road  metal  obtainable.  It  is  the  only  form  of  breaker  that  will  meet 
the  requirements  of  contracts  in  this  city,  where  grsat  attention  is 
given  to  size  and  shape  of  product.  In  fact,  we  know  th.-it  no  other 
Breaker  is  used  for  road  metal  in  this  city,  where  the  consumption  of 
granite  and  limestone  macadam  has  grown  to  enormous  proportions. 
Respectfully  yours,

by  your  firm  for  durability  and  rapid   work,  and  must   say  that  they 
e.xcel  all  breakers  we  have  yet  used.     On  an  average  we  break    1 50 
cubic  yards  of  liver  bowlders  per  day  of  ten  hours,  with  each  breaker. 
Same  have  been  in  constant  operation  for  three  years,  and  we  never 
had  any  occasion  for   expense,  worth   mentioning,  in   having  same 
repaired.    In  fact,  they  are  all  you  reprcsente'l  them  to  be. 
^'ours  trulv, 
CINCINNATI  BOWLDER  SUPPLY  CO. 
We  can  also  add,  we  have  used  the  present  head  six  months,  with 
appearances  in  favor  of  six  months  more.     We  dump  an  entire  yard 
of  bowlders  into  the  hopper  at  once. 

Once  more  yours  truly, 
CINCINNATI  BOWLLER  SUP1>LY  CO.

Gentlemen: — Yours  of  the  25th  ult.  rcceiveil  and  note  all  you  say. 
In  reply,  the  Clates  Breaker  is  all  that  can  be  desired,  and  in  fact  I 
consider  it  the  best  and  most  durable  Breaker  now  in  use,  and  it  will 
certainly  do  tnore  good  work  than  any  lioo  other  Breakers  I  ever  saw. 
I  have  used  many  different  Rock  Breakers,  but  have  abandoned  all  but 
the  Gates,  and  have  at  this  time  six  in  use.  A  head  and  good  con- 
caves will  run  from  six  months  to  one  year  without  change. 
Very  lespectfully,

ATniTsoN,  Kan.,  Fob.  19.  1R8S. 
Gentlemen: — Having  had  some  five  years'  experience  with  Rock 
Breakers,  I  wish  to  say  that  I  think  your  Size  3  Rock  Mreaker. 
owned  by  Mr.  ^V.  K.  Duttield,  and  setup  and  run  by  myself,  li.as 
the  champion  record  of  the  world.  November  3,  18S7,  we  broke 
and  screened  200  yards  of  rock  fot  concrete,  largest  size  to  go 
through  a  2%  in.  ring.  150  to  175  yards  was  an  easy  day's  work,  10 
hours.  Gray  limestone  was  the  kind  we  were  working.  We  have  a 
30  I.  II.  1".  engine,  and  run  the  Ijreaker  500  revolutions.  Never  had 
a  hot  box,  or  any  .accident  or  breakage.  If  there  is  any  Breaker 
same  size  (Size  3)  that  can  do  any  better  than  this,  please  let  me 
know;  I  would  like  to  see  it.     I  am. 

Fraternally  yours, 

H.  J.  CHAMBfiRa.

CALEDONIA  (;OLD  MINE. 

T,;rravii.i,b,  I).  T..  Sept.  24,  1888. 

Gcntknien: — Voiir  favor  of  the  4th  inst.  .it  h.-imt  and  contents 
noted.  We  have  one  .Size  6  (l.-itcs.  With  a  fx)  stamp  n'iil,  this 
saved  us  in  labor,  power,  cjc.,  some  1^27  .a  day.  With  an  80  stamp 
mill  (wliich  we  now  have)   I  calculate  about  !|!3<)  to  1^35  a  day. 

We  were  usinjj  I  Slake  breakers  No.  6,  receivinjf  openinj^s  9x15 
inches.  I'Or  an  Ho  stamp  mill  it  reciuires  4  Ulakes,  requiriiijr  3  nien, 
e.ach  u  hour  shift,  to  feed  tliem.  'Hie  lilake  action  is  not  continu- 
ous; half  the  time  is  lost  in  the  Ixickward  action.  We  ran  the  iJl.ikc 
I'.reakers  nij^ht  and  day  to  keep  the  mill  supplied.  The  dates 
Breaker  has  three  reieivin^j  openin(js,  capable  of  receiving  11x22 
inches.  Our  ore  is  very  hard;  the  larjjer  the  receiving  openings  of 
the  lireaker  are,  the  less  labor  we  require  to  break  up  the  rock  in  the 
mine.     This  saves  us  3  men  in  the  mine. 

We  run  through  the  ( lates  lireaker  2()o  tons  of  ore  in  1 1  hours  with 
two  men  feeding.  Thus  we  supply  the  broken  stone  for  the  entire 
mill  for  24  hours  by  running  the  dates  lireaker  one  shift  of  1 1  hours, 
or  running  the  lireaker  during  the  day,  and  shutting  it  down  at 
night.  This  is  a  saving  of  four  men.  lly  this  means  I  am  enableil 
to  lay  off  all  laborers  at  night  in  the  mine;  do  no  hoisting  of  rock  at 
night,  and  save  the  power  of  the  lireaker.  the  wear  f)f  machinery, 
etc.,  and  do  the  greater  portion  of  my  work  during  the  day.  This  is 
an  advantage. 

The  action  of  the  O.ates  is  continuous  and  direct.  We  could  easily 
break  with  this  lireaker  50  tons  more  of  ore  during  the  same  time. 
For  this  lireaker  we  use  about  35  or  40  Iiorse  power.  The  lireaker 
has  a  hopper  so  the  ore  does  not  have  to  be  shoveled  into  it,  but  is 
dumped  on  it,  and  for  the  greater  part  falls  into  the  openings. 

The  wear  of  the  concaves  and  head  is  not  gre.iter  than  the  wear  of 
wearing  parts  in  other  breakers.  Our  ore  is  so  very  hard  that  the 
wearing  of  these  parts  here  is  hardly  a  criterion.  We  replace  the 
concaves  every  six  weeks,  and  the  head  every  two  months.  The 
Breaker  can  be  set  up  to  break  the  ore  to  any  degree  of  fineness 
required. 

1  am  highly  pleased  with  the  Breaker,  and  consider  it  the  greatest 
improvement  made  for  years  in  this  class  of  mining  machinery. 

Any  other  infortiiation  I  can  give  yiu,  I  will  be  pleased  to  do. 
Very  respectfully, 

T.  L.  .SKINNER,

Isiil'KMiNc,  Mr'h.,  Sept.  15,  iSSS. 
Gentlemen: — In  reply  to  your  in(|uiries  as  to  the  working  of  the 
Size  2  dates  lireaker  at  the  Ropes  (lold  anil  Silver  Co.'s  mill,  would 
say  we  have  been  running  the  lireaker  continuously  for  the  past  four 
months  on  very  hard  (pKiitz,  breaking  50  to  60  tons  per  dry;  and  as 
to  the  working  of  the  machine,  would  say  I  consider  it  far  superior 
to  the  lilake,  having  used  both  here.  .As  to  wear,  the  chilled  iron 
surfaces  last  about  twice  as  long  .as  in  the  Blake,  and  break  the 
quartz  to  a  more  uniform  size  for  the  stamps,  which  we  find  a  great 
advantage.  ,My  only  regret  is  that  we  did  not  get  a  larger  Breaker, 
thereby  saving  the  amount  of  sledging  to  be  done. 
Vours  truly,

Dear  Sirs: — In  reply  to  your  incpiiries  in  relatioi.  to  the  Rock 
Breaker  you  put  up  at  this  mine  last  fall  for  exhibition,  would  say  as 
follows:  We  have  used  it  several  times  and  broke  from  150  to  200 
tons  ot  riek  copper  rock  with  it.  Some  of  the  rock  broken  contained 
from  15  to  3!;  per  cent,  of  copper,  all  of  which  passed  through  it  as 
easily  as  if  it  was  only  quartz,  or  hard  amygdaloid  rock.  The  ma- 
chine is  doubtless  rightly  named,  "The  dreatest  Rock  Breaker  on 
Earth."  I  am  fully  satisfied  that  it  is  far  superior  to. anything  of  the 
kind  now  in  use  on  Lake  Superior.

Gentlemen: — Vou  ask  my  opinion  of  your  Rock  lireaker's  capacity, 
durability,  etc.  .Mthough  we  have  the  smallest  size,  its  capacity  has 
always  exceeded  our  wants.  We  have  this  day  been  breaking  diamond 
quartz,  as  hard  as  any  in  the  Rockies,  .Tn<l  my  only  si'rprise  is  that 
the  macliine  is  not  liroken.  I  regret  we  did  not  order  a  larger  size. 
Us  operations  so  far  have  been  satisfactory,  and  I,  with  confidence 
and  pleasure,  recommend  it  to  any  in  want  of  Rock  Breakers. 
Yours  respectfully,

Fig.  37  represents  the  Plant  of  the  Cambria  Iron  Works,  erected  at  Birmingham,  Pennsylvania.  This 
Breaker  is  our  size  8,  the  largest  we  build.  The  letter  of  Mr.  John  Fulton,  the  General  Manager,  will  convince 
any  one  of  the  merits  of  this  mammoth  machine.

JNO.  Fulton,  General  Manager.  )  Johnstown,  Pa.,  Nov.  2,  1888. 

Dear  Sirs:  Your  favor  of  October  31st  received.  I  visited  the  P.irmingham  Limestone  Quarries  of  the 
Cambria  Iron  Company  yesterday,  and  found  the  large  Breaker  (tlic  riinstodt)u  of  its  class)  working  with  the 
utmost  ease.  The  machine  is  breaking  500  tons  per  day,  which  appears  to  be  less  than  one-half  the  work  of  this 
powerful  Breaker.  We  are  extending  the  quarries  to  get  the  product  up  to  700  or  1,000  tons  per  day.  The 
Breaker  does  its  work  very  easily,  and  we  estimate  that  when  we  get  up  to  700  tons  per  day  it  will  cost  us  about 
two  cents  per  ton  to  break  the  rock.  The  limestone  at  this  point  is  rather  tough,  and  requires  more  force  to 
break  it  than  the  limestone  near  your  city  of  Chicago. 

I  may  say  that  we  are  very  much  gratified  with  the  results  of  this  large  Breaker.  You  will  remember  thai, 
when  Mr.  Stackhouse  and  the  writer  accompanied  you  out  to  the  limestone  (piarry  south  of  your  city,  we  saw,  I 
think,  two  or  three  men  keeping  tiie  Breaker  open,  and  it  was  for  this  reason  that  a  larger  Breaker  was  suggested. 
Its  economical  working  shows  the  wisdom  of  this  increase  in  its  capacity,  and  I  am  not  sure  that  you  will  not  be 
urged  to  make  a  larger  one  still. 

A  number  of  persons  have  been  down  to  see  this  P.reaker  at  work,  and  they  all  return  entirely  satisfied  as 
regards  its  ability  to  do  what  is  claimed  for  it.  Without  urging  it  very  fast,  it  will  break  two  tons  per  minute 
readily.  I  think  any  reference  that  may  come  will  receive  full  satisfaction  in  every  respect  in  regard  to  the 
capacity  and  economy  of  the  machine.  Very  respectfully, 

(28)  JNO.  FULTON,  Genera/  Manager,
